The authors have created an organization at GitHub called Domain-Driven Design in PHP, which is where all the code examples from this book, additional snippets, and some complete sample projects are available. For example, you can find Last Wishes, a simple Domain-Driven Design-style application showing different examples explained in this book. Additionally, you'll find our CQRS Blog, along with Gamify, a Bounded Context that adds gamification capabilities to Last Wishes.

Finally, if you find any issue or fix or have a suggestion or comment while reading this book, you can create an issue in the DDD in PHP Book Issues repository. We fix them as they come in. If you're interested, we also urge you to watch our projects and provide feedback.
